BOAT-MOTOR.

Specification of Letters Patent.

Patented July 25, 1916.

Application led June 24, 1915. Serial No. 36,007.

To all 'whom z't may concern:

Be it known that I, EDWARD B. BLAKELY, a citizen of the United States, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Boat- Motors, of which the following is a specification.

This invention relates to a propelling device, commonly known as boat motor, of the type comprising a driving engine and a propeller associated together in a unitary structure which is adapted to be attached to the stern of a row-boat or other small craft for propelling the latter through the water.

The object of the invention is to produce an improved propelling device of this character in which the engine may be started without driving the propeller, and in which the propeller may be stopped or reversed independently of the engine. Y

The invention also refers to means whereby the starting, stopping or reversing of the propeller may be conveniently effected from the tiller.

In the accompanying drawings, Figure 1 is la vertical central section through a boat motor embodying the features of my invention, the major portion of the engine proper being omitted. Fig. 2 is a sectional view on an enlarged scale of certain parts shown at the lower end of Fig. 1. Fig. 3 isa fragmental plan view in a plane just beneath the engine, illustrating the tiller and its mounting. Fig. 4 is' a vertical section on line 4-4 of Fig. 3. Fig. 5 is a sectional detail view on line 5 of Fig. 2.

Inasmuch as the present invention does not relate to the engine proper, only a small fragment 10 thereof has been shown in Fig. 1. .The structure as a whole is arranged to be attached to the stern of a boat by means of the usual clamping bracket .11 which carries at its lower end a pair of slotted arms 12 having an adjustable connection with the structure, whereby the latter may be set at different angles with respect to the attaching bracket 11 in a manner well known.

13 is an upright drive-shaft, the upper end of which is mounted in a bearing 14 on the engine and is driven by the latter and the lower end of which is mounted in a bearing 15 fixed -to a gear casing v16. These two bearings are connected b a tube 17 which surrounds the drive-sha t 13. If desired,

this shaft may be formed in two sections coupled together by a sleeve 18 which is keyed to the two sections. The upper section may be a part of the crank-shaft of the engine. Beneath the gear casing 16 is fixed a rudder-plate 19.

On the lower end of the drive-shaft 13 within the gear casing 16 is fixed a bevel gear 20 which is in constant mesh with two opposed bevel gears 21 and 22. These two latter gears are rigidly pinned to two opposed clutch elements 23 and 24, said gears and clutch elements being rotatably mounted upon a transverse propeller shaft 25 having a propeller 26 fixed on its outer end behind the rudder-plate 19. The inner end of this shaft has a central bore 27 (Fig. 2) in which is slidably mounted a clutch shifter rod 28. A double-face clutch element 29 surrounds the propeller shaft 25 between the two clutch elements 23 and 24 and is arranged to be slid into clutch engagement with either of the latter elements. A crosspin 30 seated in the slidable clutch element 29 passes through slots 31 in the propeller shaft and fits in an opening in the shifter rod 28, whereby the slidable clutch element is rigidly secured to said shifter rod. By sliding the clutch element 29 into engagement with the coperating elements 23 or 24, the propeller may be driven in opposite directions. When the shiftable clutch element is in its central position, it is out of engagement with both of the opposing clutch elements and the propeller is idle. The shifter rod 28 slides in a bearing 32 in the gear casing 16 and through a stutling boX 33. If'desired, a spring-pressed ball or dog 34 (Fig. 5) may be seated in the bearings 32 of the gear casing in position to coperate with three recesses 35 (Fig. 2) in the shifter rod 28, said ball yieldingly holding the shifter rod in any one of its three positions.

The inner end of the propeller shaft 25 is mounted in a bearing 36 in the gear casing, and between the end of the shaft and the end wall of the bearing is preferably placed a series of anti-,friction balls 37 to take care of the end thrust on the shaft. The opposite end portion of the propeller shaft is mounted partially in a bearing 38 in the gear casing and partially in the extended sleeve or hub 39 of the clutch element 23, which in turn is mounted in a bearing 40 inthe gear casing.

" operate c `Aa An eccentric, 41 surrounds and iskeyed to the sleeve or hub 39 between the bearing 40 and 'a collar 141 fixed on the propeller shaft 25. vSaid eccentric 41 is arrangedto f ump 42 which forces water' Xthrough va'pipe 43 and circulates the water vvthrough',the jacket'` of the engine cylinder c. ward.

peller is I manuallyoperated to start,v stop or reverse`A the propeller V26 by means -tojbe' now dev-f scribed. A1 lever 44 is `pivoted at`45 on the gear casing 16 and has an angular forked lend' 46 engaging between two collars 47 on the outerv end of ythe shifter rod 28...'.lhe

opposite endof this lever is connected by a long vertical link 48 vwith the horizontal tiller 49 operated by the steersmamv This. tillcr is pivoted at 50 for movement up andr down, to a sleeve 51 which surrounds and ris rigidly fixed to the tube 17, said sleeve and tube being rotatable by the tiller to turn the rudder 19 and propeller 26 on the axis of the engine shaft. If desired, the sleeve 51 may be slotted as at 52 so that it may Abe compressed upon the tube 17 bya bolt 53. The tiller 49 comprises a yoke 54 which straddles the sleeve 51 and has a shank fitting in a socket 54 in the body portion of the tiller and detachably iixed therein by a set screw 54. The upper end of the link 48 has a yoke member 55 which is pivoted to the sides ofthe yoke 54, as-shown in Fig.

4. The til1er-49 also has suitable depending lu 56 apertured to provide guides for a slidable dog 57, one end of which is arranged toengage 1n ay series of notches 58 in the sleeve 51 to hold the tillcr in different set positions. A coiled spring 59 surrounds the dog and acts between a collar thereon and one of the lugs 56 so as to press the dog to ward said notches. The dog is arranged to be withdrawn-by means of a bell-crank lever 60v pivoted at 61 on the outer end of the tiller and connected to the dog by a link 62. It will be seen that by operating the dog 57 and shifting the tiller 49 up and down the propeller v26 may be stopped or reversed independentlyof the engine.

When the'motor isto be carried or packed for shipment, the set.. screw 54 may, if deaired, be loosened and thev tiller 49 withdrawn from the yoke 54. The dog '57 is" supported bythe tillerandv is therefore withc -v drawable withfthe latter. l ,o
